What a 90 minute timer is good for
- Soccer matches. Two 45-minute halves make 90 minutes, before stoppage time.
- Movies. Many feature films run between about 90 minutes and two hours.
- Deep work. Many people plan demanding work in blocks of about 90 minutes before a proper break.
- Sleep cycles. A sleep cycle is often said to last roughly 90 minutes, which is why some people time naps or alarms in 90-minute steps.

About this timer
The countdown runs against your device's clock from the moment you press Start, so it stays accurate in a background tab. The line under the digits shows the local time it will end. Pick one of ten alarm sounds, all generated in your browser (hear them on the countdown sounds page), and use full screen to read the time from across a room. Need a different length?

Frequently asked questions
How do I set a timer for 90 minutes?
This page is already set to 90 minutes. Press Start, or the Space bar, and the countdown begins; when it reaches zero, the alarm sounds and the page shows Time's up. Pause stops the clock and Reset takes it back to 90 minutes.
How many seconds are in 90 minutes?
5,400 seconds — that's 1 hour 30 minutes.
Is a 90 minute timer the same as 1.5 hours?
Yes. Ninety minutes is 1 hour 30 minutes, or 5,400 seconds, and the timer shows it as 1:30:00.
Will the alarm go off if I switch tabs?
In most desktop browsers, yes. The countdown is worked out from the real clock, and the alarm is scheduled with the browser's sound engine when you press Start, so it stays on time in a background tab. Phones can pause web pages when the screen locks, so keep the screen on — the timer asks the browser to do that where it can — and turn the volume up.
